How about some numbers:


Skepticalscience.com has this nice feature that you can switch between
levels of analysis clicking on the "basic", "intermediate" and "advanced'
tabs. For example:


wIll give much more detailed information.

It is true that small values of climate sensitivity cannot still be
completely ruled out. But if you accept the remote possibility of a small
value, you must also accept the possibility of a disastrously high value
like 6C, which right now cannot be ruled out either - the two extremes have
the same (small) probability of turning out correct. Focusing only on one of
the two tails of the distribution reveals bias.

I'm curious about the "proper questions" you asked those scientists, and
what kind of answers you got :-)
